Aft Platforms - rebuilding


After stripping out all the old wood and cleaning up the hull for the new, I'm at last ready to begin rebuilding the rear platforms. Here it is mostly prep'd except for vacuming the gelcoat dust.

Note the angle grinder; a crucial tool for this job.




I've got the new wood put in place. The vertical supports are used to ensure the hull is the right contour. This is the exact spot the trailer cradle pushes up. There was a single plywood rib here. I replaced the whole structure with three.
Planning note: Make sure you DO NOT fiberglass your temp supports into place! Opoxy will run on you. DOH!





New floattion shapped and put in place.

At last one, job that was easy and did not involve carcinogens







This is the semi-final product. Epoxy coated, treated 1/2" plywood screwed down to the new wood structure.
the white sheet in my weak attempt to put color into the epoxy. Save your coins. It does not work on this large a scale.







Example of how the platforms are sealed. After srewing them down, I've used more fiberblass fabric to create a water-tight seal around every edge. Water can't get in as long as nothing cracks. With as much over-strength I've created, I don't think that is an issue anymore.









View of the primary rib. It is tripple epoxied in. I used short hair jell epoxy (green) to cement all wood to the hull. I came back and ran fiberglass sheeting around all the edges to ensure no water could get under it and re-start the process of eating the wood out again. Though it is not done here yet, I'll encase it in more epoxy as the final step. It it ever breaks free, it won't be for lack of effort.
